  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Time is of the essence in plastics

    Introduction Determining the moisture content in plastics is an important step in the extrusion and molding process of many industrial resins.  Excessive moisture content can lead to microscopic steam pockets that can blister or weaken the integrity of the molded product.  Plastic pellets in a saturated or ‘wet’ state can also mislead buyers of bulk plastic since ...

  • Why measuring the ambient NO2 without conversion?

    Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...

  • Instant Loss on Ignition Results for Trommel Fines

    Cost-effective compliance with landfill tax regimes Many issues have been raised with HMRC’s proposed Loss on Ignition (LOI) testing regime for landfill taxes, including concerns that tests will take too long to be actionable and will cost too much to perform with any regularity. This may indeed be true for samples sent to a laboratory, but there is an alternative: the ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
